What is the BIGBANG ?🤔

Let us learn some information about "Big bang"

The bigbang is the name theory behind the birth of everything.That is atom,light,gravity,gases,stars,planets, galaxies and even time itself. 

And while scientists have found plenty of evidence to back up the Big Bang Theory,the name itself isn't entirely accurate. The universe didn't begin with a bang(sound didn't exist yet) or even a mighty explosion(fire and matter didn't exist either). Even light was a relatively late addition to the cosmic chronology. Confused? Here's a guide to how scientists think it all 

Big Bang breakdown.............. 

In the beginning ............ A long time ago, but time didn't exist even. Neither did space. And in this nothingness hung a supremely hot🔥 universe scrunched into a point thousands times smaller than the period at the end of this sentence. Called a "singularity",this spot might even have been smaller than an atom, the basic unit of matter. (but wasn't an atom,because atoms didn't exit yet) 

A trillionth of a trillionth of a second later................ 

Suddenly, the supremely hot, scrunched-up singularity doubles in size, and then double again,and then again - at least 90 times-in a process known as inflation. This is "bang"in the Big Bang, and it gets bigger. Expanding faster than the speed of light, this growth spurt defines the law of physics. Everything in the universe explodes into existence, but at this point it is little more than a mess of formless heat. 

One second later.............. 

Inflammation ends one million of second after the start of bigbang. The universe explanation soles and get cool. At just one second old, the newborn universe contains nature's fundamental forces, including the gravity that keeps your feet on the ground and magnetic attraction. 

Three minutes later......... 

Expansion continues protons, neutrons and electrons-the itty-bitty components of atoms- collide and interact to form a sort of super heating fog, but this mess is much too hot to allow atoms to form-fitting or even light to shine. 

400,000 years later.......... 

The hot mess cools enough for subatomic electrons to join protons and neutrons in the formation of hydrogen atoms, the most common element in the universe-and the stuff stars are made of. The fog fades so that light can finally shined, but the young universe is still without stars to create light. It continues to expansion in darkness. >
